Ok if nothing else on tv! I'm on about episode 5 I think... it's ok. It's not gripping though; it doesn't have you on the edge of your seat, and much of it is downright silly.
I find the main couple very annoying, especially the woman (doctor / paramedic or whatever she is) as she still manages to have time to put on make up during a huge crisis. Regarding the little 5'0" women fighting, I find that quite entertaining really. Bourne wasn't realistic in that respect either (men being thrown out of buildings etc and getting up)... these films are always like this, it's not meant to be realistic.
Another downside for me is there seems to be too much going on, around a number of characters, and I can't help thinking each scene is nicked from another show or film.
Watch it if there's nothing else on...
